The new information came out during interviews between Keyes, the FBI, federal prosecutors and police. Keyes was being held in an Alaska jail on charges of murdering 18-year-old Anchorage barista Samantha Koenig.

Keyes said he murdered Essex, Vt., couple Bill and Lorraine Currier in June 2011. Keyes told investigators he kidnapped the couple from their home and then murdered them in a nearby, abandoned house.

Keyes committed suicide in his cell Dec. 2, months before he was to have gone to trial. Alaska corrections officials said Keyes was mistakenly issued a razor before he committed suicide.

The recordings released Tuesday to Alaska Dispatch, an online news organization, reveal new details into the mind of the serial killer.

“I'll give you two bodies and a name,” Keyes told investigators on April 6. He told the room he would give out information, but not all at once.

Fifty minutes into the taped conversation, an investigator pulled out a photo of the Curriers. Another investigator asks Keyes, “Are those the two people you killed?” to which Keyes said, “Yep.”

Keyes later told investigators they would be able to find the Curriers’ bodies in four plastic bags in the basement of a house on Upper Main Street in Essex.

Investigators in Vermont searched the site, which had been demolished since the Currier murders.

On April 12, investigators told Keyes the home had been demolished.

“If they had bothered to pull everything out of the basement, they probably would have found them,” Keyes said. “I'm guessing they just buried it,” Keyes said about the homes material.

“They’re going to have a hard time finding any evidence now obviously I mean except for the bodies,” Keyes said. “I'll still tell the story like what happened.”

Keyes also told investigators he threw his gun, and a gun taken from the Currier home, into a New York reservoir.

He said before he was arrested in February 2012, he was planning to return to Vermont to burn the farmhouse and possibly churches as well.

Keyes also asked for the death penalty, saying he would waive his rights to a trial.“You told us that you wanted the death penalty and you wanted it within one year,” an investigator said. “Yup,” Keyes said. “I don't want all this other stuff hanging over my head while I sit in supermax somewhere waiting for the next thing to come down the pike.”

Keyes admitted to robbing a Tupper Lake N.Y. bank in 2009. He said he was planning to make more robberies while he was in the North Country and as he drove to Burlington.

He said it was during that trip when he buried guns and other equipment later used to kill the Curriers.

“I had three banks staked out in different towns, starting quite a ways north of Burlington,” Keyes said. “There's I think Highway 15 went up north and did like a loop and there were several towns along that route.”

Route 15 runs from Winooski to Morrisville.

With the help of mapping software, Keyes pointed out where investigators could find stashed kits and where he stayed in June 2011.

Keyes said if he were caught in the act, he would get in a shootout with police.

“I’d rather go out while I still have some sanity and good memories,” he said, laughing.

Keyes said he wanted to speed up the death penalty process and his time with investigators for his daughter’s sake.

Investigators believe Keyes murdered at least eight people across the country. Some have estimated that number could be 11 or more.
